Description

*Important Note*: Thank you all for your incredible support. We are taking the OsciPrime Oscilloscope one step further. The new application on the market ( http://goo.gl/UhgYf ) will have all the features plus new multi touch support and is also available as Open Source under http://www.osciprime.com .

This is the Open Source Oscilloscope based on the Bachelor Thesis "Using Android in Industrial Automation" of the University of Applied Sciences of Northwestern Switzerland.

Note that this application is written for an embedded system for high speed data acquisition (runs on the Beagleboard) and this is a port to the phone/tablet platform.

It will use the microphone as input source, "USB" will only work with the hardware board from our project.

Features:-> (NEW) Tablet support-> Mic Input, only working mono 44100[Hz] at the moment.-> Cursor, Trigger, Offset-> If you want to use it with our board (schematic at http://android.serverbox.ch) up to dual 6 [Msps], 8 bit A/D, no root needed :).

Important Note:

Tested on Nexus S, HTC Magic, LG P500 and Acer A500 3.1 Tab

Nifty Took me a while to figure out how to turn it on. To display audio waveform via microphone: Menu, [ S ], Source Selection: Audio

Decent oscilloscope! I got this as my school's CRO was damaged and I needed to teach a lesson on sound waves. Needless to say it does its job well but it would be good if you could change background colour for higher contrast.

Cool but need improvement Missing the most essential feature of showing the frequency/division. Impossible to know what I am actually measuring. The "t:340" label is not help either. Second: A great idea is to build a frequency down-converter probe so we can measure more than 22 KHz with audio port!

No instructions No info on how to use this at all ... no specs nothing... I realize all phone are different but you could at least say that .... it also isn't intuitive on how to change the range or the time scale ... also all the menu options use abreviations that dont make any sense ... long story short this app sucks and the basics are too hard to understand and you'll be spending more time figuring it out than actually using it

**** PLEASE ENSURE THE GABOTRONICS DEVICE IS UP TO DATE!!***** USB SUPPORT ****** (only for android 3.1 and greater) The newest and best input option is a USB hardware device provided by Gabotronics. USB host mode has now been compatible since android 3.1, therefore most new phones and tablets will support USB host mode (Please check device). NFX Oscilloscope supports the Gabotronics Xprotolab/Xminilab, this has 2 analogue input channels and 8 digital channels and measures a tiny 2.5 x 4 cm!! The device it's self is a cheap portable alternative to most mainstream oscilloscopes, and has many different features. Connecting the Xprotolab to the NFX Oscilloscope provides a powerful and cheap oscilloscope platform for your portable needs. For more information on the Xprotolab or Xminilab click the following links.http://www.gabotronics.com/development-boards/xmega-xprotolab.htmhttp://www.gabotronics.com/development-boards/xmega-xminilab.htm

So match this application with the cheap device from gabotronics and you will get a great portable oscilloscope!Note: Only the analogue channels and logic Channels are supported on the xprotolab/xminilab, future updates will bring digital and tone generator support.

Currently the USB mode has been tested on Samsung Galaxy Nexus , Asus Transformer , Asus Nexus 7 , Samsung Galaxy S3There has been problems reported with android version 4.3 and USB host, there is a major bug in the release, which is set to be updated at some point in the future.

Please note : Most devices will need a OTG cable to enable usb host mode. See phone specific instructions for more information.

***** Microphone SUPPORT ******The second option is the microphone input to the android device. This can be used to attach a scope lead to the jack socket. More information can be found at the following website.http://www.instructables.com/id/A-Preamplifier-for-Smartphone-Oscilloscopes/Features include, triggering for different impulse and continuous signals. In addition to this there is level measurement and fundamental frequency readings

It is possible to control the amplitude, time/div and trigger level whilst monitoring. Settings included trigger directions, sample rates and voltage span calibration.

Have a look at this blog for more scope cable information from a fellow user of Nfx oscilloscope.http://www.instructables.com/id/A-Preamplifier-for-Smartphone-Oscilloscopes/

Head to my blog for more information on the NFX Oscilloscope. http://nfxdevelopment.wordpress.com/

If you are unhappy in anyway with this product, feel free to contact me and I will help all I can, if I cannot help I will offer a refund at any time (even past the 15 minute google refund mark)

Thank you for purchasing, I hope you enjoy! If you have enjoyed this app leave a quick rating and comment. Thanks!!

Android Bluetooth Oscilloscope.It can be used with a phone or tablet without a computer.This means there is no any wired connection to the phone or tablet, which can guarantee the safety of your device.The oscilloscope is the most frequently used, most flexible device for electric measurements.It visualizes an electric potential over time function, producing much more information than other potential and current measurement methods.With an oscilloscope the following quantities can be either directly or indirectly measured:direct voltage, alternating voltage, direct current, alternating current, time, time delay, phase, phase difference, frequency to view live waveforms, make measurements.

This program turns your device into a simple oscilloscope function of the spectrum analyzer, signal source is the microphone input of your device. With this program you will be able to compare the level of noise (sound) in different areas or from different sources, as well as to determine the spectrum of audio signals. You can take a picture signal by moving the program mode pause and examine in greater detail the form and spectrum of individual sections of the signal.The spectrum of the signal is determined using FFT.

Combined with the LabNation SmartScope, this app turns your tablet into a mobile oscilloscope/waveform generator.

Howto's available on our https://www.youtube.com/channel/UCYpUzMIaVfcYDJbrzyaE1ig/feed">youtube channel

Check the SmartScope tech specs at https://www.lab-nation.com/specs

NOTE: If you cannot install this app, it probably means your device doesn't support USB on-the-go. This means you can't use the SmartScope. If you'd like to try the app still, you can download the android package (APK) from our website at https://www.lab-nation.com/download

General Features: - Has a 'Keep Alive' option for the screen in the menu. - All answers from the calculators can be copied to clipboard if you wish to move the answers to a 'proper' android calculator etc. - All answers can be Shared amongst other Android Apps that support the Androids 'text' format. (SMS, eMail, Viber etc etc etc) - All screens are scrollable and scalable so should support the smallest (~120ppi) resolution devices right up to the largest tablets out there!

Hobby sound pressure meter (SPL) for your device!It has cool analog VU meter and oscilloscope. It can be used to verify if a sound is at same level for measuring loudspeaker response. The app is intended for fun and it does not provide accurate measurement in decibels.100% Ad free!

SensorScope plots the output of your phone's sensors, similar to a traditional oscilloscope. With SensorScope you can select ANY sensor of your phone, including all synthetic and corrected sensors, you can pause the plot, and you can zoom in and out on the time and value scales.

Use it if you are developing an app that uses sensors, to measure your environment, to learn about the physical phenomena that these sensors measure, or simply if you are curious.

When it makes sense, you can plot the X, Y, and Z component, and the magnitude. For Wi-Fi and Bluetooth you can plot the strongest signal, or a chosen network.

Not all Android devices have all sensors, and some even have `fake' sensors that always return zero. The sensors indicated with (*) are `virtual', `synthetic' or `fused' sensors that combine or process data from other sensors.

This application help you calculate the approximate frequency and period, when using a non-menu driven oscilloscope. If you are not sure of the formula to calculate what you see on the display, this calculator will help. just enter the X axis (time) coordinates and the number of division on the display it takes to complete a full cycle and press the 'Calculate' button. That's all there is to it, the frequency and period will be displayed.

DroidTesla is a simple and powerful SPICE engine.SPICE is an acronym for Simulation Program with Integrated Circuit Emphasisand was inspired by the need to accurately model devices used in integrated circuit design.

DroidTesla simulator solves basic resistive circuits using Kirchoff’s Current Law (KCL) in much the same way a student in a circuits class would,the simulator systematically forms a matrix in accordancewith KCL and then proceeds to solve for the unknown quantities using various algebraictechniques such as Gaussian elimination and sparse matrix techniques.

For non-linear components, such as the diode and BJT ,DroidTesla engine searching for the approximate solution by making an initial guess at an answerand then improving the solution with successive calculations built upon this guess.This is called an iterative process.DroidTesla simulation uses the Newton-Raphson iterative algorithmto solve circuits with non-linear I/V relationships.

For reactive elements(capacitors and inductors),the DroidTesla uses numeric integration methods to approximate the state of the reactive elements as a function of time.DroidTesla offers the Trapezoidal(I'll add a GEAR method later) integration methods to approximate the state of the reactive elements.Although for most circuits, both methods will provide almost identical results,it is generally regarded that the Gear method is more stable, but trapezoidal method is faster and more accurate.
